Insulation materials with higher thicknesses have lower long-term thermal conductivity values in general. The density of rigid polyurethane foam (PUR/PIR) used for building thermal insulation typically ranges from 30 to 45 kg/m3. For some applications, however, it can achieve 100 kg/m3.
Answer:
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
The answer is microvilli.
Answer:
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.
